Question

The formula for finding the area A of a triangle is
given by A = 1/2bh, where b and h represent the base and the height of the triangle respectively.
(i) If b = 20 cm and h = 45 cm, find the area of the triangle.
(ii) If A = 30 cm^2? and b = 10 cm, find the height of the triangle.​

Answer 1

Answer:

i) 450 cm²

ii) 6 cm

Step-by-step explanation:

Subquestion 1:

Given: b= 20cm, h= 45cm

Therefore,

A = 1/2bh

= 1/2•20•45

= 450 cm²

Subquestion 2:

Given: A= 30cm², b = 10 cm

A = 1/2bh

30 = 1/2•10•h

30 = 5h

h = 30/5

Therefore h = 6cm
